The Monkey falls from the tree at the same time as a banana pellet is launched. The monkey catches the pellet in his mouth. This demo (best done in real life) shows that both the projectile (ball) and the monkey are both being acted upon by the same accelerating force due to gravity.
Here is a 20 slide PowerPoint looking at the effect of gravity on projectiles, it starts by asking can road runner really just float in the air, until he realises he has run off a cliff. In class using a projectile launcher, we test the impact of gravity, asking if we were to only go […]
A neat little worksheet, which gets students used to rearranging and substituting numbers into the 5 given kinematic equations. Answers included. Great to use at the start of kinematics / linear motion after proving how the formulas are generated.
